Bal Seal to launch high force spring for oilfield connecting

Bal Seal Engineering, Inc. has announced plans to launch the Enforcer™ high force canted coil spring, a mechanical fastening component that gives oil and gas equipment designers the ability to mate critical parts with precisely controllable insertion and removal forces — from 500 to more than 10,000 lb — over multiple service cycles.

Bal Seal Engineering, a provider of custom-engineered sealing, connecting, conducting, and EMI shielding solutions, says the Enforcer provides “repeatable, heavy-duty latching with minimal axial play,” and offers an alternative to disposable shear pins and complex ball detent assemblies. The spring, which can be piston or housing mounted, can also be engineered with relatively low insertion force to simplify the reattachment of parts. Available in a variety of materials, including stainless steels and nickel-based alloys, the spring leverages advanced manufacturing capabilities to offer up to a 10X increase in force over the company’s existing Bal Spring™ product line.

When made from a nickel-based alloy wire material with a diameter of 0.031 in., Enforcer high force canted coil springs with a 1-in. ID demonstrated an initial removal force of over 2000 lb, and maintained a removal force of more than 1700 lb after five cycles. In independent testing, larger diameter Enforcer springs consistently demonstrated removal forces greater than 10,000 lb.

The company says it added the Enforcer to its spring product offering in answer to a growing demand for more cost-effective high-force latching options in downhole tools (LWD/MWD, plug setting, retrieval), subsea valves, and other similar oil and gas equipment applications.

“Bal Seal Engineering has a long history of success with its sealing and connecting technology in the oilfield market,” says Bal Seal Global Energy Market Manager Jim Harty. “With the launch of innovative products like the new Enforcer high force spring, we’re extending our experience to help oilfield customers meet their high force fastening requirements as well.”
